New LDD version fields (#27)

[tdddblog]

See https://github.com/NASA-PDS/pds-registry-mgr-elastic/issues/27 for more info.

Test Instructions

• Delete old registry if exists. Create new registry.

  registry-manager delete-registry
  registry-manager create-registry

• Download latest Cassini LDD from https://github.com/pds-data-dictionaries/ldd-cassini/blob/main/build/development/888e3ee0842d927caf24f7d97bb3fced2de58bdc/1.13.0.0/PDS4_CASSINI_1D00_1500.JSON to some folder, for example, /tmp/schema/
• Run Registry Manager load-dd command to load the LDD.

  registry-manager load-dd -dd /tmp/schema/PDS4_CASSINI_1D00_1500.JSON -ns cassini

• Check that both im-version and ldd-version fields have values in Elasticsearch registry-dd index for new Cassini LDD. Old LDDs will only have im-version. (You can open the following URL in a browser)

  http://localhost:9200/registry-dd/_search?q=class_name:LDD_Info+and+attr_name:cassini
